Recently have become interested in the 35/14 ART lens, mainly based on several terrific samples. Great reviews also but SOME reports of inconsistent AF. There is also a Sigma AF dock, but it's another 60$.

So the question: will MFA work in case there is a front/back focussing issue?

Kind regards,

AFMA technically works with any lens. However, it may not eliminate all focus inaccuracies with third party lenses. I use a Sigma 30mm ART, and had a slight misfocus issue with a 70D, and AFMA did fix the issue most of the time, but not all. Sigma uses reverse engineering to make their lenses, and use AF algorithms from other Canon lenses, which may cause issues.

Thanks. I am slightly worried about reports of inconsistent focussing with this lens, some say to be totally frustated with it (a minority) and most reviews say it's dead on accurate.

Is there a quick and dirty test that I can do, at the person I buy it from, without big screen computer evaluation? Aim at the middle of a ruler carefully avoiding recompose and enlarge on screen? That's how I would normally do it. Would that reveil any issues? Maybe both near and far?
